Cleaning Carpet-Sweeper Brushes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates toa cleaning device, and particularly to such a device designed to be used to clean the refuse which collects in the brushes of carpet sweepers and vacuum cleaners. As is well known to the users of carpet sweepers and similar devices, the lint from the carpet and the dust and other refuse, including hair, become attached to the brush and embedded in the bristles thereof. The said refuse collects in a thick mass and, owing to the presence of threads, hair and other fibrous material, becomes so firmly embedded in and attached to the brush that it is removed with great difiiculty. It is a com-.

mon practice to remove such refuse with a fork, button hook, or other common implement, but such a process is slow, tedious and exasperating. 7

It is an object of this invention to provide a device which can easily be held and'manipulated and by means of which the massed material in the brush can be readily removed therefrom.

It is another object of the invention to provide such a device comprising a body portion having depending therefrom rows of spaced teeth having their lower ends formed as a substantially horizontally disposed hook.

It is a further object of the invention to provide such a device having one end of sub stantially rectangular form and having its other end tapered to a narrow width with rows of teeth depending from said body and a wide space between adjacent rows of said teeth near the center of said body.

These and other objects and advantages of the invention will more fully be set forth in the following description made in connection with the accompanying drawings in which like reference characters refer to the same parts throughout the different views,

front end. apertures 1n and depend from the-member 1 the sweeper.

vice, the side portion beingshown in vertical section, and V I I Fig. 2 is a bottom plan view of the device. Referring to the drawings, the device comprises a body portion comprising a plate 1 of wood, metal or other suitable material,

the rear end of which is of rectangular form but'which tapers to a narrow width at it's Spaced teeth 2 pass through and have their lower ends 3 of semi-circular.

The inner ends of the plates 1 and 5, there is an extra wide space 6 for a purpose to be later described. A. curved handle 7 is provided preferably having fiat ends secured to the top of plate 5' by fastening nails or screws 8.

In operation, the device is held firmly in one hand by the handle 7 and the device moved across the brush of the carpet sweeper, the longitudinal axis of the device moving transversely of the longitudinal axis of the brush. The device is given a slight rocking motion as it moves across the brush and the mat of refuse which is attached to the brush is firmly engaged by the teeth 3.

and lifted bodily from the brush. The material after being thus detached from the brush of the sweeper can readily be removed from the cleaning device by grasping the same with two of the fingers of one hand and by moving the fingers transversely. through the space 6. A few strokes of the device are sufficient to clean the brush of The large numberof the teeth 1 3 get such a hold on the mass of matted material in the sweeper that the same is readily removed therefrom and the mass of material is not torn and shredded as is the case when it is attempted to remove the, same with one pin or hook. The-pointed shape of the device at one end enables it to be conveniently manipulated at one end of the brush and in places where there is small space for the use of the same. The pointed shape is also of great advantage if it is de sired to move the device longitudinally of 7 the groove in which the sweeping brush is usually disposed. teeth 3 act to readily engage and securely hold the mass of matted materiel so that the same can be readily lifted from the brush bristles in e matted or felted sheet. By so removing the matted material the same is not disintegrated and dropped about on the floor. The device has been used in actual practice and found to be exceedingly successful and efiicient for the purpose intended. The same can easily be made at small expense and at the same time made very strong and durable.

it will, of course, be nnderstoochthet verious changes may be made in the form, details, proportions and arrangement of the parts Without departing from the scope of epplicents invention, which, generally stated, consists in the matter shown and The curved ends of the reeneos described and set forth in the appended claims.

What is claimed is:

1. A device of the class described cemprising a flat bedy, teeth depending therefrom having their ends formed hooks, said teeth being arranged in transverse rows, two of said rows adjacent the center of said brush having an extra Wide space therebetween.

2. A. de *ice of the class described comprising a flat body having one end considerably Wider than the other and tapered toward the latter end substantially to a point, teeth depending air in said body having their ends formed as substantially horizontally disposed hooks, said teeth being arranged in transverse rows.

In testimony whereof I eflix my signature.
